El valor de la dignidad humana frente a la tecnociencia

The expansion of technoscience, which integrates science, technology, and intervention in living organisms, reconfigures the meaning of humanity and raises the problem of how to safeguard dignity as an ethical limit. This study proposes to critically analyze this tension and derive guiding criteria. A qualitative and exploratory literature review of recent academic works and institutional statements was conducted, using criteria of quality and relevance, searches in recognized databases in Spanish and English, critical reading, and thematic categorization around conceptions of dignity, ethical challenges, and normative proposals. The findings identify two decisive vectors: the reduction of the person to data, which subordinates uniqueness to decision models and compromises autonomy, equality, and reparation; and biotechnological intervention in identity, which strains personal continuity, authenticity, and integrity, with intergenerational implications. Conceptual gaps and the urgency of human rights impact assessments and accountability mechanisms are also noted. It concludes that dignity must operate as a cross-cutting principle in the design, regulation, and use of emerging technologies, through conceptual clarification, ethical indicators, and transdisciplinary public policies that reconcile innovation with respect for the intrinsic value of the person.
